Embodiment Construction

[0010] Below in conjunction with embodiment and attached figure 1 , 2 The present invention is further described. An adjustable differential instrument for measuring miniature bearings, including: a three-jaw chuck 1 and a differential instrument 5; the three-jaw chuck 1 includes a disc body 2 and a jaw 3; the inside of the jaw 3 is provided with a step 4 .

[0011] The process of measuring the outer diameter of miniature bearings, the specific steps are: the bearing outer ring of the bearing to be tested is fixed on the steps of the jaws of the three-jaw chuck, the jaws are fixed on the bearing to be tested, and then the outer diameter of the bearing to be tested is measured using a differential meter. Measurement.

[0012] The above schematically describes the present invention and its implementation, which is not restrictive, and what is shown in the drawings is only one of the implementations of the present invention, and the actual structure is not limited thereto. Th...

Abstract

The invention relate to an adjustable difference amplitude meter for measuring a miniature bearing, which comprises a three-jaw chuck and a difference amplitude meter, wherein the three-jaw chuck comprises a chuck body and clamping jaws; and the inner side of each clamping jaw is provided with a step so as to be convenient for fixing an outer ring of the bearing. The bearing to be measured is fixed through the three-jaw chuck, thereby being convenient for a surveyor to adjust the meter, and improving the work efficiency. Compared with a present difference amplitude meter which only can measure a bearing of a fixed size, the device and the measurement process provided by the invention can measure all models of bearings with the outer diameter being 5-30mm, and the measurement precision is + / -0.001mm.

Description

technical field [0001] The invention belongs to the field of instruments used for bearing measurement and detection, in particular to an adjustable differential instrument for miniature bearing measurement. Background technique [0002] At present, for the measurement of bearings, it is usually used to place the bearing to be measured on the column, and then use the differential instrument to measure, only a single type of bearing can be measured; when different bearings need to be measured, the corresponding column needs to be replaced, so the measurement is not necessary Convenience and low work efficiency. Contents of the invention [0003] The object of the present invention is to provide an adjustable differential instrument for measuring miniature bearings, which has a reasonable design and improves work efficiency. [0004] The technical solution of the present invention is: an adjustable differential instrument for measuring miniature bearings, including: a three-...
